Description

  The present invention relates to a meteorometer in which devices for observing meteorological elements such as rain sensitivity such as temperature and humidity and wind direction and wind speed are collectively arranged.

  A meteorometer has been proposed in which instruments for observing meteorological elements such as precipitation, temperature, sunshine duration, wind direction and wind speed are arranged together. Such a meteorometer functions as an unmanned weather station and transmits observation data to a predetermined computer by wire or wirelessly (Patent Document 1).

  In general, since such a meteorometer is managed unattended, regular maintenance or repair work in the event of a failure is performed by a specialized worker who has knowledge of the meteorometer.

  However, early maintenance and repair work are necessary to ensure the continuity of observation data. For this reason, if the maintenance, repair work, etc. can be entrusted to a person close to the place where the meteorometer is installed, the weather observation can be resumed at an early stage.

  On the other hand, if a large number of such meteorometers can be installed in a narrow range, various types of meteorological elements can be collected with high density, and for example, it can contribute to predicting the occurrence of unique meteorological phenomena in a specific area. For this reason, it is desired to reduce the cost of meteorometers and install a large number of meteorometers in a small area with a small budget at high density.

  1 and 2, the meteorometer 1 of the present embodiment is attached to a support column 2 erected on the ground or the like via an L-shaped attachment bracket 3. The meteorometer 1 includes a first unit 10, a second unit 30, a third unit 60, and a fourth unit 80. Data of various weather elements observed by the meteorometer 1 are transmitted to a predetermined server via, for example, a wired or wireless communication line.

  The first unit 10 is detachably attached to the upper part of the second unit 30, the third unit 60 is detachably attached to the lower part of the second unit 30, and the fourth unit 80 surrounds the third unit 60. Removably attached to the lower part of the second unit 30. In the meteorometer 1, the first unit 10, the second unit 30, and the fourth unit 80 are arranged in a line in the vertical direction.

  Here, in FIG. 1B, the two orthogonal axes passing through the center point O are the X axis and the Y axis, the right side in the X-axis direction across the center point O is the E side, the left side is the W side, and the center point O is The upper side in the Y-axis direction is the N side and the lower side is the S side.

  The first unit 10 includes an inverted concave roof portion 12 having a spherical roof surface 11 and a disk-shaped ceiling portion 14 having, for example, a mirror-like ceiling surface 13. The first unit 10 and the second unit 30 are assembled together by screwing the ceiling portion 14 to the upper ends of the four support columns 15 provided in the second unit 30. As shown in FIG. 1B, the four support columns 15 are arranged on the same circumference around the center point O of the ceiling portion 14, and have an angle of 45 degrees with respect to the X axis (Y axis). It is arranged.

  The roof surface 11 is provided with a rain sensor 16 as a rain sensor for detecting in real time that it has started raining, and a window portion 17a desired by the solar sensor 17 as a solar sensor for detecting solar radiation in real time. Is done. The roof portion 12 can be removed from the ceiling portion 14 with screws (not shown).

  As shown in FIGS. 2 and 3, the ceiling part 14 is provided with the solar radiation sensor 17 on the upper surface corresponding to the window part 17 a.

  The rain-sensitive sensor 16 has a capacitance type configuration in which a plurality of conductive patterns are arranged on a printed circuit board, and is arranged in the concave portion 11 a of the roof surface 11. The inclined rain sensor 16 detects rain using the fact that both conductive patterns are short-circuited when raindrops are deposited across adjacent conductive patterns. The bottom surface of the recess 11a is inclined downward at an angle of 20 degrees, for example, and raindrops falling on the printed board are slid along the inclined printed board surface to improve drainage.

  The solar radiation sensor 17 is constituted by a photodiode, for example, and is arranged in parallel with the rain sensor 16. Communication lines (not shown) of the rain sensor 16 and the solar radiation sensor 17 are connected to a circuit unit arranged in the second unit 30 through the hollow support column 15.

  An engaging piece 15 a is formed at the upper end of each column 15. The engagement piece 15 a is formed with a communication hole portion 15 c that communicates with the screw hole portion 15 b and the hollow portion of the support column 15. On the lower surface side of the ceiling portion 14, a recessed portion 14 a that engages with the engagement piece portion 15 a is formed. The recess portion 14a is formed with a screw insertion hole 14b corresponding to the screw hole portion of the engagement piece portion 15a and a hole portion 14c through which the communication line is inserted corresponding to the hollow portion of the support column. Therefore, the ceiling portion 14 is fixed to the column 15 by screwing a screw (not shown) into the screw hole portion of the engagement piece portion 15a through the screw insertion hole 14b.

  The second unit 30 is a first cylindrical part 31 that is an outer cylindrical part formed in a cylindrical shape, and an inner cylindrical part that is formed on a square cylinder disposed inside the first cylindrical part 31. The upper surface of the 1st cylinder part 31 and the 2nd cylinder part 32 is obstruct | occluded by the upper-plate part 33.

  In the first cylindrical portion 31, a connection port portion 34 that performs communication with an external power source and the outside is disposed in a recessed portion 311 formed in the outer peripheral portion on the E side. Transmitting / receiving elements 351 to 354 of the ultrasonic anemometer 35 are arranged on the upper surface of the upper plate portion 33. The first transmitter / receiver element (abbreviated as H1 element) 351 and the third transmitter / receiver element (abbreviated as H3 element) 353 constitute a first sensor unit for transmitting and receiving, and the second transmitter / receiver element ( A second sensor unit that performs transmission / reception is configured by combining the H2 element (abbreviated as H2 element) 352 and the fourth transmission / reception element (abbreviated as H4 element) 354. Here, as shown in FIG. 4, the H1 element is arranged on the E side, the H2 element is arranged on the S side, the E3 element is arranged on the W side, and the E4 element is arranged on the N side. Further, the H1 element 351 and the H3 element 353 are arranged symmetrically with respect to the center point O, and similarly, the H2 element 352 and the H4 element 354 are arranged symmetrically with respect to the center point O. Furthermore, the H1 element 351 to the H4 element 354 are arranged between the support columns 15, and the first sensor unit and the second sensor unit have measurement intervals orthogonal to each other and set equal measurement intervals.

  As shown in FIG. 5, the H1 element 351 to the H4 element 354 are directed in a direction in which the transmission / reception surfaces 355 face each other and are inclined obliquely upward at a radiation angle of 45 degrees to 60 degrees. The ultrasonic waves radiated from the transmission / reception surface 355 of the H1 element 351 to H4 element 354 are reflected by the ceiling surface 13 of the roof portion 12 and enter the transmission / reception surface 355 of the opposing H1 element 351 to H4 element 354. . The wind direction and the wind speed are measured by measuring the propagation time of the ultrasonic wave between the H1 element 351 and the H3 element 353 of the first sensor unit and the propagation time of the ultrasonic wave between the respective elements of the second sensor unit. Here, assuming that the sound speed is Vs and the wind speed is Vw, the sound wave propagates from the windward to the leeward at a speed of Vs + Vw, and propagates from the leeward to the windward at a speed of Vs−Vw. Therefore, the wind speed can be measured by measuring the propagation time of the ultrasonic waves of the first sensor unit and the second sensor unit. Further, the wind direction can be measured by arranging the first sensor unit in the north-south direction and the second sensor unit in the east-west direction, for example.

  In this embodiment, when the distance between the H1 element 351 and the H3 element 353 facing each other and the distance between the H2 element 352 and the H4 element 354 facing each other are, for example, 3 cm to 10 cm, the wind speed can be measured with high accuracy. .

  Moreover, since the anemometer 35 has a reflective configuration using the ceiling surface 13, ultrasonic waves can be transmitted to a space free of obstacles between the H1, H2, H3, and H4 elements and the ceiling surface 12. Therefore, a highly accurate wind direction and wind speed can be measured. Moreover, the wind direction and the wind speed can be measured by the roof portion 12 in a state where it is hardly affected by rain or snow.

  On the other hand, as shown in FIGS. 6 to 11, the first cylindrical body portion 31 has ribs 36 extending from the inner peripheral wall portion toward the center point O from four locations along the X-axis direction and the Y-axis direction. Each rib 36 is formed over substantially the entire length of the cylindrical portion 31 in the vertical direction. Each rib 36 has an inner end surface integrally connected to the outer peripheral wall surface of the second cylindrical portion 32 to form a space 37 on the side.

  That is, the 2nd unit 30 comprises the double wall structure which has arrange | positioned the 2nd cylinder part 32 inside the 1st cylinder part 31, and the temperature in the 2nd cylinder part 32 is a temperature change of external temperature. I am trying not to be affected. This is because the atmospheric pressure sensor 50 as the atmospheric pressure sensing means for sensing the atmospheric pressure in real time is arranged in the second cylindrical body portion 32, so that changes in atmospheric pressure due to temperature changes are reduced. As the atmospheric pressure sensor 50, a piezo element is used.

  On the outer periphery of the upper end of the first cylindrical body portion 31, a flange portion 38 is provided in the circumferential direction that hangs downward and has a convex curved surface. That is, when the cross wind against the wind direction anemometer 35 hits the flange 38, the wind is smoothly guided to the space between the upper plate portion 33 and the ceiling surface 14 so that the wind direction and wind speed can be detected with high accuracy. .

  A bottom cover 39 is disposed on the lower end surface of the second cylindrical portion 32, and the lower surface opening of the second cylindrical portion 32 is closed with the bottom cover 39. The bottom cover 39 is detachably fixed by screwing the screw 40 into the screw hole portion 32a of the second cylindrical body portion 32.

  In addition, a communication port 312 that communicates the inside and the outside of the cylindrical body portion is formed in the upper end portion of the first cylindrical body portion 31 in the circumferential direction at appropriate intervals. That is, the atmospheric pressure inside the first cylindrical body portion 31 (including the inner side of the second cylindrical body portion 32) is made the same as the external atmospheric pressure via these communication ports 312. In addition, a gap is formed between the first cylinder part 31 and the second cylinder part 32, so that outside air is taken into the first cylinder part 31 but rain is prevented.

  As shown in FIG. 5, in the internal space of the second cylindrical body portion 32, a main board 41 to which the atmospheric pressure sensor 50 is attached and a sub board 42 are arranged at right angles to the main board 41.

  FIG. 9 is a view of the main board 41 as viewed from below the cylindrical body portion 31, and FIG. 10 is a view of the back surface side of the upper plate portion 32 with the main board 41 and the sub board 42 removed. The sub board 42 is provided with a driver circuit such as various sensors mounted on the meteorometer 1, for example, and the main board 41 is provided with a circuit unit for calculating and processing the measurement results of the various sensors. The main board 41 appears as shown in FIG. 9 when the bottom cover 39 is removed.

  In the present embodiment, a cartridge type temperature / humidity cylinder 61 constituting the third unit 60 is detachably attached to the bottom cover 39.

  As shown in FIGS. 2 and 7, the temperature / humidity cylinder 61 is inserted into the mounting hole 39 a formed in the bottom cover 39 by pushing the upper end 62 formed in the cylindrical shape of the temperature / humidity cylinder 61. A connector 63 provided at the upper end 62 of the temperature / humidity cylinder 61 is inserted into and connected to the temperature / humidity sensor connector 43 provided on the substrate 41. A flat portion 64 for positioning is formed at the upper end portion 62 of the temperature / humidity cylinder 61. When the temperature / humidity cylinder 61 is attached so that the flat portion 64 faces the positioning plate 39b provided on the upper part of the temperature / humidity sensor connector 43, the connectors 43 and 63 are connected smoothly.

  A rubber O-ring 65 is attached to the outer peripheral portion of the upper end portion 62 of the temperature / humidity cylinder 61. When the temperature / humidity cylinder 61 is inserted into the mounting hole 39a, the O-ring 65 is brought into frictional contact with the inner peripheral surface of the mounting hole 39a. For this reason, the temperature / humidity cylinder 61 is held in the mounting hole 39a with friction by the O-ring 65, and is prevented from falling off.

  A flange portion 67 is formed on the base side of the temperature / humidity cylinder 61. A water-tight seal member 66 formed of a rubber plate is attached to the lower end side of the flange portion 67. And the temperature / humidity cylinder 61 is pushed in until the flange part 67 contact | abuts to the opening end surface of the mounting hole part 39a.

  On the other hand, the upper end portion 68 a of the wiring board 68 extending in the vertical direction is fixed to the upper end portion 62 of the temperature / humidity cylinder 61. A temperature sensor 69a and a humidity sensor 69b are arranged on both sides of the lower end portion 68b of the wiring board 68. A protective cylinder 70 formed in a cylindrical shape with a porous member such as polyethylene is covered around the lower end 68b of the wiring board 68 with a gap. Since the protective cylinder 70 has air permeability, it does not affect the temperature and humidity detection of the temperature sensor 69a and the humidity sensor 69b. Further, by providing a net member on the bottom surface of the protective cylinder 70, insects and the like are prevented from entering the protective cylinder 70. The protective cylinder 70 is fixed by screwing the upper end opening into the upper end 62.

  The temperature / humidity cylinder 61 of this embodiment replaces the third unit 60 constituting the temperature / humidity cylinder 61 and the like when the temperature sensor 69a and the humidity sensor 69b are out of order. When the third unit 60 is replaced, since the temperature sensor 69a and the humidity sensor 69b are covered with the protective cylinder 70, there is no trouble that the hand touches the temperature sensor 69a and the humidity sensor 69b.

  In the present embodiment, the temperature / humidity cylinder 61 is pushed in as a method of attaching the third unit 60 to the second unit 30. However, the present invention is not limited to this. For example, the upper end 62 of the temperature / humidity cylinder 61 is provided. It is good also as a structure which inserts in the mounting hole part 39a, rotates around a predetermined angle axis | shaft after that, is engaged, and prevents dropping. In this case, by allowing the wiring board 68 to rotate with respect to the upper end portion 62, only the upper end portion 62 is allowed to rotate in a state where both the connectors 43 and 63 are coupled. Also, a plurality of protrusions are provided on the outer peripheral portion of the upper end 62 of the temperature / humidity cylinder 61, and a vertical guide groove that engages the protrusions along the vertical direction around the opening of the mounting hole 39a. And a circumferential groove along the circumferential direction leading to the upper end of the guide groove. By setting the lower surface side of the circumferential groove as an inclined surface, the protrusion moves upward along the inclined surface, and the seal member 66 is sandwiched between the flange portion 67 and the opening surface of the mounting hole 39a.

  As shown in FIG. 7, a battery cover 39 c is detachably attached to the bottom cover 39. When the battery cover 39c is removed, a part of the main board 41 appears, and a battery 47 such as a nickel hydride battery secondary battery or a dry battery can be replaced. A dip switch 48, a USB connector 49, and the like are arranged on the main board 41 that appears in the opening of the battery cover 39c. Further, on the main board 41, for example, a push button type power switch 52 is arranged. An operation hole 39d is formed in the bottom cover 39 corresponding to the switch 52, and the power switch 52 can be turned on and off from the outside through the operation hole 39d. The operation hole 39d is closed by a plug member (not shown), and the plug member is removed when the power switch 52 is operated. The bottom cover 39 is provided with a pilot lamp 53 that clearly indicates the operating state and the communication state.

  Further, as shown in FIGS. 6 to 8, a first engagement portion 54 formed in an arc shape is provided around the bottom cover 39 so that the ventilation cylinder 81 constituting the fourth unit 80 is detachably attached. Yes. The engagement structure of the fourth unit 80 by the first engagement portion 54 will be described later.

  As shown in FIG. 2, the fourth unit 80 has a ventilation cylinder 81. The ventilation tube 81 is formed by integrating a plurality of cylindrical umbrella members 811 to 814 with an interval in the vertical direction.

  The ventilation tube 81 includes a first umbrella member 811, a second umbrella member 812, a third umbrella member 813, and a fourth umbrella member 814 from bottom to top, and the second umbrella member 812 and the third umbrella member 813 are Same structure. In the present embodiment, the first umbrella member 811 to the fourth umbrella member 814 have the same basic outer shape, and the top surface (not shown) of the first umbrella member 811 is closed. The first umbrella member 811 to the fourth umbrella member 814 have a mirror-finished outer surface to prevent a temperature rise due to the influence of solar radiation. The first umbrella member 811 to the fourth umbrella member 814 paint the inner surface black and absorb radiant heat.

  In addition, circular openings (not shown) are formed on the top surfaces (not shown) of the second umbrella member 812 to the fourth umbrella member 814. The inner diameters of these openings are formed larger than the outer diameter of the protective cylinder 70. A cylindrical second engaging portion 82 that is removably attached to the first engaging portion 54 through the temperature / humidity tube 61 in the openings of the second umbrella member 812 to the fourth umbrella member 814 is provided above the ventilation tube 81. Is provided. On the inner peripheral side of the second engagement portion 82, a pressing cylinder portion 83 formed in a cylindrical shape that abuts the lower surface of the seal member 67 disposed below the flange portion 66 of the temperature / humidity cylinder 61 is formed. Yes. On the inner wall surface side of the second engagement portion 82, engagement protrusions 82a are formed at three locations along the circumferential direction toward the center portion. On the inner peripheral surface of the second engaging portion 82, flat portions (not shown) whose inner surfaces are flat surfaces are formed at three locations in the circumferential direction, and engaging protrusions 82a are formed on the flat portions.

  In the first engagement portion 54, a flat portion 54a having a flat outer peripheral surface side corresponding to the engagement protrusion 82a corresponds to the flat surface formed on the inner peripheral surface of the second engagement portion 82. The screw holes 54b are formed in the flat portion 54a. In the flat portion 54a, an engaging groove portion 54c that engages with the engaging protrusion portion 82a is formed. The engagement groove 54c is connected to the first engagement groove (not shown) in which the engagement protrusion 82a engages in the vertical direction and the first engagement groove, and the engagement protrusion 82a is engaged in the circumferential direction. A second engaging groove (not shown) to be joined, and a lower side surface of the second engaging groove is formed as an inclined surface that becomes higher upward as the distance from the first engaging groove increases.

  Therefore, in order to attach the second engagement portion 82 of the ventilation tube 81 to the first engagement portion 54 of the bottom cover 39, the flat portion formed on the inner peripheral surface of the second engagement portion 82 is the first engagement. When aligned with each flat portion 54a of the portion 54 and pushed in as it is, each engagement projection 82a engages with the first engagement groove of the engagement groove 54c, and when further pushed, each engagement projection 82a is second. It is pushed to the connection position with the engaging groove. When the ventilation cylinder 81 is rotated clockwise, each engagement protrusion 82a moves upward while sliding on the inclined lower side surface of the second engagement groove.

  Therefore, the pressing cylinder 83 presses the flange 67 against the bottom cover 39 together with the sealing member 66 of the temperature / humidity cylinder 61, and the sealing protrusions 82a are further moved upward along the second engaging grooves by the sealing members. The flange 67 is pressed against the lower surface of the bottom cover 39 while elastically deforming 66. For this reason, the temperature / humidity cylinder 61 is prevented from falling off by the ventilation cylinder 82.

  Further, when the ventilation tube 81 is rotated to a predetermined position, the screw insertion holes 84 of the second engagement portion 82 are aligned with the screw hole portions 54b of the first engagement portion 54, and a set screw (not shown) is inserted through the screw. The screw holes 54b are screwed through the holes 82b to prevent the ventilation cylinder 81 from rotating in the direction around the axis.

  The first umbrella member 811 to the fourth umbrella member 814 are integrally fixed with a predetermined interval via an attachment member (not shown). An appropriate gap is formed between each opening and the protective cylinder 70 to ensure ventilation.

  In addition, since the top surface of the first umbrella member 811 has no opening and the uppermost surface of the ventilation tube 81 is closed by the bottom cover 39, a fast wind flow does not occur in the ventilation tube 81 in the vertical direction. For this reason, the temperature change by the influence of a quick wind is prevented for the protection cylinder 70. FIG.

  In the present embodiment, the outer diameter of the ventilation cylinder 81 is smaller than the outer diameter of the first cylinder portion 31 of the second unit 30. For this reason, before and after the sun reaches the zenith, the ventilation cylinder 81 is shaded by the first cylinder portion 31 and is not directly exposed to sunlight, so that the ventilation cylinder 81 can be prevented from being heated. In addition, since the surfaces of the first umbrella member 811 to the fourth umbrella member 814 are mirror-finished, it is possible to eliminate the influence of the temperature change in the ventilation tube 81 due to the irradiation of sunlight. Therefore, the temperature sensor 69a and the humidity sensor 69b housed in the protective cylinder 70 can accurately measure the temperature and humidity.

  In the meteorometer 1 configured as described above, whether or not the meteorometer 1 is operating normally can be determined by looking at the pilot lamp 53 from the lower side of the second unit 30. If not normal, the ventilation tube 81 of the fourth unit 80 is removed from the second unit 30 as shown in FIGS. 6 and 7. Next, the plug member blocking the operation hole 39d of the bottom cover 39 is removed, and the push button type switch 52 is pushed from the operation hole 39d to turn off the entire electric circuit. When the battery is simply exhausted, the battery 47 exposed by removing the battery cover 39c can be replaced as shown in FIG.

  Since part of the main board 41 is exposed by removing the battery cover 39c, a communication cable of a personal computer for diagnosis is connected to the USB connector 49 when inspecting the state of the electric circuit. At that time, the dip switch 48 and the like are set according to a predetermined manual, and the meteorometer 1 is diagnosed.

  If the failure of the temperature sensor or the humidity sensor is diagnosed, it can be dealt with by removing the ventilation cylinder 81 and replacing the temperature / humidity cylinder 61 of the third unit 60. At that time, since the temperature sensor and the humidity sensor are not directly touched, the occurrence of a failure or the like can be prevented in advance.

  When it is diagnosed that the atmospheric pressure sensor 50 has failed, the bottom cover 39 is removed from the main body 33 and the main board 41 is replaced. At that time, only the atmospheric pressure sensor 50 may be exchanged.

  If it is determined that the wind direction anemometer 35 has failed, the second unit 30 is replaced. In this case, the second unit 30 can be separated by removing the support column 15 from the first unit 10 and removing the third unit 60 and the fourth unit 80 from the second unit.

  When the rain sensor 16 or the solar radiation sensor 17 is diagnosed as a failure, the first unit 10 is replaced.

  As described above, the meteorometer according to the present embodiment can easily replace parts without requiring a special technique. For this reason, it becomes possible to entrust maintenance management etc. to the person near the installation place of the meteorometer 1.
